Hi!

I use this powershell commands for listing firewall rules:

Get-NetFirewallRule -Direction Inbound | Select-Object Name, DisplayName, Description

Show-NetFirewallRule | where {$_.enabled -eq true' -AND $_.direction -eq inbound'}| select displayname

With these commands I can't see rules applied through GPO. Does anybody know how can I accomplish this?

Thank you!

Best regards.

    Update!

    I've managed to get it using this command:

    Get-NetFirewallRule -PolicyStore ActiveStore | Where-Object {$_.Description -eq "My_GPO"}

    As per MS we must user -PolicyStore for GPO applied policies.

    Now, my question is what gives this rule a Name because I can see it is some kind of guid and can I locate this guid Name on a computer (the name my GPO has is under DisplayName:

    Hi,

    The name is a random GUID generated by the NewGuid() method.
    https://learn.microsoft.com/en-us/dotnet/api/system.guid.newguid

    You can use the GUID to locate the firewall rule with the Where-Object cmdlet.
